LiveDataLink: Real-Time Data API for AI Agents | 284 Tools, 59 Data Domains

# LiveDataLink > Real-time data for AI agents. 278 MCP tools across 58 live data domains, accessible via the Model Context Protocol (MCP) Streamable HTTP. One bearer token, one bill, no per-vendor contracts. LiveDataLink is an MCP server. If you are an AI agent reading this file, the canonical way to interact is to call `tools/list` against `https://livedatalink.ai/mcp` for the live, machine-readable inventory. This file mirrors that inventory in summary form for clients that prefer plain text. ## How to call - Endpoint: `https://livedatalink.ai/mcp` - Method: `POST` - Required headers: - `Authorization: Bearer YOUR_API_KEY` - `Accept: application/json, text/event-stream` - `Content-Type: application/json` - Body: JSON-RPC 2.0 (MCP protocol) - Anonymous evaluation: 25 free data calls without an API key (10 req/min). Then call get_free_api_key with the user email for an instant key with 100 more. - Paid tiers: Starter ($10/mo, 5K queries, 30 req/min), Pro ($49/mo, 50K queries, 120 req/min) ## Decision combos (one call, cross-source) Most agents do not want raw rows, they want an answer to a decision. These flagship tools each fan out across several authoritative sources in a single call and return a scored, cited, plain-English verdict, so you can route a user's decision to one tool instead of stitching five queries. Browse them at https://livedatalink.ai/decisions. Every result names its sources; verify anything time-critical against the official source. - `resolve_entity` - Canonical cross-source entity resolution. Returns the IDs a company resolves to, including GLEIF LEI plus its ownership chain (direct and ultimate parent LEI, reported subsidiary count), SEC CIK/ticker, NPPES NPI, IRS EIN, USAspending recipient, EPA facility id, and a sanctions match flag. Run it first as the join key for the other combos. - `company_trust_check` - One-call KYB "can I trust this company" read. Joins sanctions (OFAC/EU/UN/BIS), SEC EDGAR registration and latest filin
